Board bring up activities and test peripherals from U-boot.

Hi..To Everybody ,
i have just started my journey in Embedded linux, currently working on Cirrus Logic board(EP9315) and i have the data sheet and schematics of the board,so now i would like to test all the peripherals (like.. uart,Ethernet), just basic test
like writing some data to that particular register and signals are happening on that bus,so here my focus is to ask where to start this from software side...i was told to test from u-boot before linux up but i don't know where in u-boot i start testing...

kindly, Please let me know as soon as possible for this solution and if anybody provided extra information (regarding u-boot and board bringing up activities) i would be pleased with ur knowledge.

Thanks and Regards
Bhaskar
